Group M comprised trauma patients requiring massive transfusions(>10 units of packed red blood cells) within 24 hours of emergency admission. Group C comprised patients with an injury severity score >9 but not requiring massive transfusions. Levels of f T3, free thyroxine(f T4), and thyroidstimulating hormone(TSH) were evaluated on admission and on days 1, 2, and 7 after admission. The clinical backgrounds and variables measured including total transfusion amounts were compared and the inter-group prognosis was evaluated. Results are presented as mean±standard deviation.RESULTS: Nineteen patients were enrolled in each group. In both groups, 32 were men, and the mean age was 50±24 years. In group C one patient died from respiratory failure. The initial f T3 levels in group M(1.95±0.37 pg/m L) were signifi cantly lower than those in group C(2.49±0.72 pg/m L; P<0.01) and remained low until 1 week after admission. Initial inter-group f T4 and TSH levels were not significantly different. TSH levels at 1 week(1.99±1.64 μIU/m L) were higher than at admission(1.48±0.5 μIU/m L) in group C(P<0.05).CONCLUSION: Typical NTIS was observed in trauma patients requiring massive transfusions. When initial resuscitation achieved circulatory stabilization, prognosis was not strongly associated with NTIS.展开更多
